The issue stems from the cam phaser design itself relating to a pin designed to lock into place after the engine shuts off. However, this pin will not always lock into place, so the phasers spin freely before enough oil pressure has been generated, thus causing a rattle.
Replacing phasers will sometimes cure the problem but often rattle comes back within a few months. The sure fix to phaser problems is to lock the variable cam timing by essentially turning the phaser into a fixed timing gear. The WMS Cam Phaser Lockout kit will solve the phaser issue permanently.
How do I quiet down my cam phaser noise?
You can decrease the cam phaser noise by using an oil treatment. This is a cheap stop gap fix which may buy you some time but ultimately you will have to go for the permanent repair option.
